Solution: Implement Two Stacks Using One Array
Explore how to design and implement two stacks sharing one array by managing pointers at opposite ends. Understand push and pop operations that maintain fixed size without resizing, with O(1) time complexity, enabling you to write efficient JavaScript stack structures.
We'll cover the following...
Statement
Design a data structure TwoStacks, that represents two stacks using a single list, where both stacks share the same list for storing elements.
The following operations must be supported:
push1(value): Takes an integervalueand inserts it into the first stack.push2(value): Takes an integervalueand inserts it into the second stack.pop1(): Removes the top element from the first stack and returns it.pop2(): Removes the top element from the second stack and returns it.
Note: Perform all operations in-place without resizing the underlying list, maintaining a fixed size throughout.
Constraints:
list.length...
